Silver-phosphorus-copper brazing ring
Silver-phosphorus-copper brazing filler metal is a kind of air self-brazing filler metal with moderate melting point and good fluidity. It is widely used in statistical brazing of copper alloy parts in refrigeration, motor, instrument and other industries. With the help of phosphorus self-brazing flux, silver-phosphorus-copper brazing brass and bronze need not be brazed with additional flux, but phosphorus-containing solder can not be used for steel brazing. Brazing methods include flame brazing, furnace brazing, induction brazing and resistance brazing.
